The purpose of this work is to plan and control task oriented configuration changes in a metamorphic robotic system, formed by a colony of axisymmetric holons moving to inspect pipe inner surfaces. The metamorphic robotic system in question, is a reconfigurable robotic structure made up of identical, independently controlled, mechatronic modules (holons) constituting a colony. The holons in that colony have very limited individual task abilities and are only capable of connecting, disconnecting and rotating about their center of symmetry while climbing over other holons. But it is only when they come together to form a colony that they can be used as a robotic system to perform many tasks, such as pipe surface inspection. The metamorphic inspection system has the advantages of robust reconfigurability, that can only be achieved by an efficient adaptable control mechanism which results from the difficult motion-planning problem for the colony. In this work, we consider three well-known motion-planning strategies that make use of different heuristics: "The Short Path Algorithm, The Artificial Potential Algorithm and The Sub-Goals Algorithm", and in order to generate an adaptable motion-planning and control strategy in possibly changing environments and achieve the best result in any environment, out work proposes to use all three strategies together, combined with the principles of the "mixed strategy" of Game Theory. The general path-planning strategy that we develop in this paper, switches from one of the three strategies to another, so that, at every step, the most suitable strategy is used and a result better than or equal to the "best" of the three strategies is achieved in all cases.

A Control System Architecture for Control of Non-Affine in Control, Open-Loop Unstable Underactuated Systems Marangoz, Alp; Kutay, Ali Türker (2017-07-25) In this paper, a control system architecture for control of non-affine in control, open-loop unstable underactuated system is discussed. Passivization of the unactuated (internal) system dynamics achieved through perturbation of trajectories of the actuated states, which are calculated through adaptive dynamic inversion technique, based on Tikhonov's theorem. Performance of the controller is shown through simulation of two open-loop unstable and locally uncontrollable example problems.
DYNAMIC COGNITIVE FORCE CONTROL FOR AN AUTOMATIC LAND EXCAVATION ROBOT Bodur, M; Zontul, H; Ersak, Aydın; KOIVO, AJ; YURTSEVEN, HO; KOCAOGLAN, E; PASAMEHMETOGLU, G (1994-04-14) The automation of the land excavation machines can find applications in the excavation of soil in both terrestrial and planetary mining and construction. The automation requires planning at different levels such as task and trajectory pre-planning, and the automatic execution of these pre-planned tasks. In the execution of the pre-planned digging trajectories, the unexpected soil properties along the trajectory raises problems such as excessive ram-forces that may harm the machine, or cannot be applied beca...
Computational-Experimental Design Framework for Laser Path Length Controller Fenercioglu, Tevfik Ozan; Yalçınkaya, Tuncay (2021-08-01) The application areas of piezoelectric materials are expanding rapidly in the form of piezo harvesters, sensors and actuators. A path length controller is a high-precision piezoelectric actuator used in laser oscillators, especially in ring laser gyroscopes. A path length controller alters the position of a mirror nanometrically by means of a control voltage to stabilize the route that a laser beam travels in an integral multiple of laser wavelength. The design and verification of a path length controller p...
The staminal lever mechanism and floral diversity of some bee-pollinated Salvia L. (Lamiaceae) species Atalay, Zeynep; Doğan, Musa; Department of Biology (2011) The characteristic staminal lever mechanism is defined as a functional unit including the modification of stamens into lever-like structures, their reversible movement and the organisation with the remaining floral structures and they are involved in the process of pollen transfer. The staminal levers play a major role in the process of pollen deposition on the pollinators’ body and their proportion and interaction with pollinators may have significant consequences for the pollination system in Salvia. In t...
Computational modeling of self-assembly in deformable bodies Bilgin, Koçak; Göktepe, Serdar; Department of Civil Engineering (2021-9) Self-assembly is a process in which an irregular system transforms into a regular pattern or an organized structure through local interactions between the components of the material without any external influence. Therefore, self-assembly has great potential in the synthesis and manufacture of new materials. Although the main focus in the literature is mostly on self-assembly at the molecular level, there are many exciting applications of the self-assembling processes at larger scales. Space and time-varyin...
